The cluster's "name" is only the file-system's directory path.

You can easily rename this directory, as long as you pass the relevant 
directory name to pg_ctl's -D parameter (which tells PostgreSQL which 
database "cluster" to use.)

It goes without saying, don't move the directory while PostgreSQL is 
running.
